Groupon launched with more than 25,000 coupons from over 5,500 brands and retailers in North America, including Target, Best Buy, Nordstrom and Macy’s. Next year, Groupon hopes to expand the business internationally and add in-store coupons.

“This could have meaningful potential over time,” said Sterne Agee analyst Arvind Bhatia.

The online coupon market is worth about $4 billion a year and when in-store coupons are included, the total addressable market increases to $28 billion, Bhatia noted, citing industry estimates.

“This gives people another reason to check Groupon first when they’re shopping,” said Rich Williams, senior vice president of global marketing at GRPN, to the newspaper.
